Abstract (en)
[origin: EP0651353A1] A data processing system for a picture coding, includes a data memory for storing a DCT coefficient data successively transferred one after another, a flipflop set prior to the successive transfer of the DCT coefficient data, and a non-zero detector for detecting a non-zero data when the DCT coefficient data is successively transferred. When the non-zero data is detected, the non-zero detector resets the flipflop. When the successive transfer of the DCT coefficient data has been completed, An entropy coding CPU discriminates on the basis of the condition of the flipflop whether or not all of the data stored in the data memory is zero, so that if the condition of the flipflop indicates that all of the data stored in the data memory is zero, the entropy coding CPU does not read the data memory. <IMAGE>
